Overcoming Communications Outages in Inverter Downtime
In reality, inverter-related production losses are much more variable, although data from large-scale surveys of fielded systems are rare. Here we present a method of detecting inverter
Hereby, this paper focuses on the central inverter Failures Causes Analysis (FCA). Hence, this paper presents a new methodology of FCA-B-FSA which studies the inverter Failures Causes Analysis (FCA) based on the Fault Signatures (FSs) as a main objective, then the outcomes link each Fault Signature (FS) to the corresponding Root Cause (RC).
The central inverter is considered the most important core equipment in the Mega-scale PV power plant which suffers from several partial and total failures. This paper introduces a new methodology for Failure Causes Analysis (FCA) of grid-connected inverters based on the Faults Signatures Analysis (FSA).
This paper reviewed several publications which studied the failures of the PV power plant equipment's and presented that the central inverter failures rate is the highest for the PV power plant equipment's which affected negatively in both PV power plant availability and ROI.
Some authors discuss inverter failures due to the issues of reactive power control. The PV inverters operate at unity power factor, but as per the new grid requirements, the PV inverters must operate at non unity power factor by absorbing or supplying reactive power to control the grid voltage and frequency.
